The model's core directive is to leverage state-of-the-art Chain-of-Thought (CoT) distillation primarily sourced from Claude-4.6 Opus interactions.\n\nThrough Supervised Fine-Tuning (SFT) focusing specifically on structured reasoning logic, this model excels in breaking down complex user problems, planning step-by-step methodologies within strictly formatted `<think>` tags, and ultimately delivering precise, nuanced solutions.\n\n## 🗺️ Training Pipeline Overview\n\n```text\nBase Model (Qwen3.5-4B)\n │\n ▼\nSupervised Fine-Tuning (SFT) + LoRA\n(Response-Only Training masked on \"<|im_start|>assistant\\n<think>\")\n │\n ▼\nFinal Model Text Only (Qwen3.5-4B-Claude-4.6-Opus-Reasoning-Distilled)\n```\n\n### 🧠 Example of Learned Reasoning Scaffold（Example）\n\nThe model includes targeted optimizations addressing Qwen3.5’s tendency toward excessive transitional or repetitive reasoning on simple queries. Through deep distillation and structural imitation of Claude-4.6-Opus reasoning chains, the model adopts a more efficient structured thinking pattern:  \n**“Let me analyze this request carefully: 1..2..3...”.**  \nThis streamlined reasoning paradigm significantly reduces redundant cognitive loops while preserving deep analytical capacity, resulting in substantially improved inference efficiency.\n\n```text\nLet me analyze this request carefully:\n\n1. Identify the core objective of the problem.\n2. Break the task into clearly defined subcomponents.\n3. Evaluate constraints and edge cases.\n4. Formulate a step-by-step solution plan.\n5. Execute the reasoning sequentially and verify consistency.\n            .\n            .\n            .\n```\n\n### 🔹 Supervised Fine-Tuning (SFT)\n- **Objective:** To inject high-density reasoning logic and establish a strict format for problem-solving involving an internal thinking state prior to outputting the final response.\n- **Method:** We utilized **Unsloth** for highly efficient memory and compute optimization. A critical component of this stage is the `train_on_responses_only` strategy, masking instructions so the loss is purely calculated over the generation of the `<think>` sequences and the subsequent solutions.\n- **Format Enforcement:** All training samples were systematically normalized so the model strictly abides by the structure `<think> {internal reasoning} </think>\\n {final answer}`.\n\n### 📈 Training Loss Curve\nThe training loss showed a strong and healthy downward trend throughout the run, demonstrating effective knowledge distillation. Starting from an initial loss of **0.74356**, the model converged steadily to a final loss of **0.23984** — indicating the model successfully internalized the structured `<think>` reasoning patterns from the Claude 4.6 Opus teacher data.\n\n### 📚 All Datasets Used\nThe dataset consists of high-quality, filtered reasoning distillation data:\n\n| Dataset Name | Description / Purpose |\n|--------------|-----------------------|\n| [nohurry/Opus-4.6-Reasoning-3000x-filtered](https://huggingface.co/datasets/nohurry/Opus-4.6-Reasoning-3000x-filtered) | Provides comprehensive Claude 4.6 Opus reasoning trajectories. |\n| [TeichAI/claude-4.5-opus-high-reasoning-250x](https://huggingface.co/datasets/TeichAI/claude-4.5-opus-high-reasoning-250x) | Injecting high-intensity, structured reasoning instances. |\n| [Jackrong/Qwen3.5-reasoning-700x](https://huggingface.co/datasets/Jackrong/Qwen3.5-reasoning-700x) | Additional curated reasoning samples designed to strengthen structured step-by-step problem solving and improve reasoning diversity. |\n\n## 🌟 Benchmark\n\n| Benchmark | Baseline (4B) | Distilled (4B) |\n|-----------|---------------|---------------|\n| GPQA Diamond (0-shot) | 33.82 | **38.88** |\n| AI2 ARC-Challenge (25-shot) | 64.59 | **66.38** |\n\nThese evaluation results were originally reported by khitsly.\nEvaluation was conducted using the EleutherAI `lm-evaluation` with 8-bit inference and temperature 0. Higher scores indicate better performance.\n\n## 🌟 Core Skills & Capabilities\n1. **Modular & Structured Thinking:** Inheriting traits from Opus-level reasoning, the model demonstrates confident parsing of the prompt, establishing an outlined plan in its `<think>` block sequentially rather than exploratory \"trial-and-error\" self-doubt.\n2. **Extended Context Support:** Fine-tuned smoothly with a 16,384 token context window allowing complex multi-step reasoning traces to exist gracefully within memory limits.\n\n## ⚠️ Limitations & Intended Use\n- **Hallucination Risk:** While reasoning is strong, the model remains an autoregressive LLM; external facts provided during the thinking sequence may occasionally contain hallucinations if verifying real-world events.\n- **Intended Scenario:** Best suited for offline analytical tasks, coding, math, and heavy logic-dependent prompting where the user needs to transparently follow the AI's internal logic.\n- This model is a test version intended solely for learning and demonstration purposes, and is for academic research and technical exploration use only.\n## 🙏 Acknowledgements\nSignificant thanks to the [Unsloth AI](https://unsloth.ai/) team for making rapid fine-tuning of large LLM models accessible. Additionally, we acknowledge Qwen internally, and the open-source community developers producing exceptional distilled datasets (`nohurry` and `TeichAI`).",
